You can put this solution on YOUR website!
Before I continue with this rather complicated problem, perhaps you should look at my newly posted Lesson Plans in algebra.com under the topic of Exponents. There is a lesson on Positive Exponents and a lesson on Zero and Negative Exponents. These lesson plans are complete with the explanations, examples, exercises, and answers to all the exercises that you need to do. \r

\n" ); document.write( "\r
\n" ); document.write( "\n" ); document.write( "Is that what you had in mind? I think this is right. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First, when you raise a power to a power, you multiply the exponents:
\n" ); document.write( "\"+%28x%5E3%2A+Y%5E%28-2%29%2A2%5E2%2Ax%5E%28-6%29+%29+%2F+%28x%5E%28-8%29%2A+y%5E4%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next, when you multiply with the same base number, you must add the exponents:
\n" ); document.write( "\"+%28x%5E%283%2B%28-6%29%29%2A+Y%5E%28-2%29%2A4+%29+%2F+%28x%5E%28-8%29%2A+y%5E4%29\"\r
\n" ); document.write( "\n" ); document.write( "\"+%28x%5E%28-3%29%2A+Y%5E%28-2%29%2A4+%29+%2F+%28x%5E%28-8%29%2A+y%5E4%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you divide with the same base number, you must subtract exponents:\r
\n" ); document.write( "\n" ); document.write( "\"+x%5E%28-3-%28-8%29%29%2A+Y%5E%28-2-4%29%2A4+\"
\n" ); document.write( "\"+x%5E5%2A+Y%5E%28-6%29%2A4+\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Do you remember that \"y%5E-6+\" means \"1%2Fy%5E6\"? You had better see my Lesson Plan if you didn't know that!!\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"+x%5E5%2A+Y%5E%28-6%29%2A4+\"\r
\n" ); document.write( "\n" ); document.write( "\"x%5E5%2A%281%2F%28y%5E6%29%29%2A4\"
